The application of phosphorus bioassays developed to identify the nutritional status of plant roots have been applied to ectomycorrhizal and saprotrophic fungal hyphae. With increasing phosphate supply, a decrease in influx of radiolabelled phosphate solution in the test was seen in all fungal species, similar to the response found in plant roots. The ectomycorrhizal species Hebeloma crustuliniforme had more than twice the P influx rates of the other fungi, suggesting a potentially greater scavenging ability than the other species tested. There appears to be no significant difference in influx rates between saprotrophic and mycorrhizal fungal species. The range of influx values between isolates of the same ectomycorrhizal fungal species was generally less than that between species. This technique could be used as a means of selection of efficient ectomycorrhizal species and isolates for inoculation programmes.
